How big (or small) could animals get?
BBC Wildlife
|February 2022
WITH EVOLUTIONARY BIOLOGIST JV CHAMARY
-
Animals come in a range of sizes. The smallest are from a group called Myxozoa, jellyfish-like parasites about one-hundredth of a millimeter long that are only visible under a microscope. Among vertebrates you would recognize with the naked eye, the smallest known to man is Paedophryne amauensis, a tiny frog that is just 8mm long.
How large can animals grow?
The heaviest beasts to ever walk the Earth were long-necked sauropod dinosaurs, known as titanosaurs. With a mass of about 50,000kg, titanosaurs weighed the same as 10 elephants and yet were still three times lighter than the largest species of all time, the blue whale, at 150 tonnes. Aquatic mammals often have a mass-to-volume ratio that matches the density of water, which provides neutral buoyancy and supports weights that can’t be reached on land due to size limits.

What's the largest animal gathering on Earth?
PEOPLE LOVE A PARTY. BUT AS POPULOUS as our species is, the headcounts at our gatherings don't match those of other species. The Maha Kumbh Mela, a Hindu pilgrimage in Prayagraj, India, drew more than 660 million people in January 2025. But this horde - thought to be the largest in human history – pales in comparison to the groups formed by our animal relatives.

Do plants have memory?
TO HAVE TRUE MEMORY AN ORGANISM requires brain cells to store experiences through the action of sophisticated neurotransmitters. Plants lacking brain cells therefore cannot be said to have that capacity for memory. However, there is evidence that some plants adapt their characteristics based on 'remembered' experiences.
